Configuration interaction calculations result in a total molecular energy of 99.34% of the experimental value, and a dissociation energy of 89.33% of the experimental value in LiH. Similar calculations in Li2 result in 99.40% and 89.9%, respectively, for these two numbers. The energy of atomic Li, which enters the dissociation energy calculation, is calculated to comparable accuracy (99.42%).
